I have a 1.5 years old baby, I’m Tech Lead in one of our company projects, I have a babysitter taking care of my son from 9 to 6 when I work as much as I can and then I leave my computer behind and spent my time with my baby. Weekend are also family only time, basically a baby give me a better work-life balance.

I occasionally talk at local meetups where I go with my son and partner.

A baby will negatively affect your career only if you let it do it. Most of the time it will not and you will be happier than ever spending time with it.
